T0 @ZZ whom @'25 may concern Be it known that'I, EDWARD FISH, a citi- Zen of the United States, and a resident; of

VNew York, -boroughof Manhattan, in the county of New vYork and State of New York, have invented certain newiand useful Improvements in Feeding Devices, of which the following is a specification.

This invention relates to feeding vdevices for sheet blanks .and particularly to means therein for directing the blanks while being fed. It has foi` its object to provide a device of the kclass specified, simple in construction, eiiicient in Operation and which tends to maintain the blank in its previous direction of travel. Y

Vith these ends in View and others which will appear hereinafter my improvements comprise features illustrated in the drawing .accompanying this specification, wherein:

Figure 1 is a plan view of my device apy plied, for purposes of illustration, to a maployed for making envelopes from blanks' of irregular outline, such as shown at 2 in Fig. 1, the blanks are stacked as at 3., and said blanks are lifted one at a time to the position of blank 2, Fig. 2, by some known means such as gummed pickers, not shown. From there the blank is advanced in the direction of arrow A, Figs. 1 and 2,'to the folding box 4 through which it is pushed downwardly by the usual plunger, not shown. In advancing the blank from its position 2 to the folding box, the tendency of the gum 5 on the bottom flap of the envelope combined with the impact againstthe air is such as often to cause the leading end ofthe blank to bend downwardly, resulting in the collision of that leading end with the edge of the table orl other intervening parts of the machine, to the displacement or destrucblank out of its rectilinear travel, thereby delivering the blank at the folding box in skewed position, resulting in a defectively folded envelope.

By my improvements these objectionable features are obviated, as will appear in the following detailed description. Transfer table 6 lies in a plane slightly above that of the top of bed plate 7 and said plate is cut away at 8 to receive the bent down delivery end of said table. Said plate is also cut away at 9 to receive stem 10 of table 6. Said stem terminates downwardly in pivot 11, Fig. 4, which turns in the upper and inner arm of lever 12. Said lever is pivotally mounted at 13 in bed 14. Lever 12 may be Oscillated from cam 15 through roll 16 on rock-arm 17, the upper end of which is connected with the outer end, 12a, of lever 12 by link 18. Roll 16 is urged to engagement with cam 15 by pull spring 19. For maintaining table 6 in parallelism of movement from the position of Fig. 1 to that of Fig. 3, stem 10 is provided with arm 20 fixed thereto, and fixed to post 13 is arm 21 of equal length and extending in the same direction. Said arms 20 and 21 are connected by link 22. By this means table 6, as it moves from the position of Fig-1 to below the blank, as in Fig. 3, maintains its leading end 6 normal to the path of the envelope blank to the folding box. After table 6 reaches the position of Fig. 3 the envelope blank is advanced in the direction of its arrow A, thereover, by means not shown but well known in the art. Coincidently, said table is returned to its position of Fig. 1, preferably before the leading end of the blank passes entirely over said table, thereby bridging gap 8 in bed plate 7 and preventing theleading end of the blank from hooking into said gap. It will be observed that during the movementof said table 6 from the position of Fig. 3 back to that of Fig. 1, the leading end of blank 2 will lie thereon .and that any movement of said table in a direction other than that in which it is desired to advance the blank will tend to cause that blank to deviate from that desired direction of travel. For instance, if said table was rigidly secured to lever 12, said table would travel concentrically only and would tend to lead the blank with it, awayv from bination of a movable transfer table adapted to support the leading end of the blank, and means for moving said table in an arcuate pathv in a plane parallel to that of V-the'blank and in parallelism laterally with the path of said blank.

2. In a blank feeding mechanism the combination of a lever mounted for oscillation y ina plane parallel to that of the blank, a

transfer table 'pivotally mounted on the free end of said lever, and means coacting withV said lever for moving saidtabl'evin an arcuate path in a plane parallel to that of thev blank and in parallelism laterally with the path of said blank. Y

3. In blank feeding means the combination of an oscillating lever, a transfer table pivotallyfattachedto the free end kofv said lever, and a link, one end of Whichis pivotally connected to' said table ata point other than Where said table is connected toV said lever and the other end of Which is piv otally connected to a fixed part. f
